These measures, which foster domestic shipbuilding by enabling shipping companies to receive fee refunds for purchasing American-made vessels, were influenced by a petition from unions like the United Steelworkers and the AFL-CIO. This petition, which called for an investigation into China's shipbuilding industry practices, led to a finding during the previous administration, confirming the detrimental impact on U.S. commerce.

David McCall, president of the United Steelworkers, stated that the government's investigation vindicated their claims and expressed optimism about the potential restoration of U.S. shipbuilding capacity due to these new regulations.
